I booked ticket on 09.05.2019 for journy on 16.06.2019 for Coimbatore to Patna. I booked the seat 7E & 7F for my journey, and the same is mentioned in my ticket. However when we asked for the boarding pass, seat they have allotted was 17A, 17B for Coimbatore to Bengaluru and 12A, 12B for Bengaluru to Patna journey. I requested them to see my booking details and accordingly change my seat. All the counter staff and manager were asking for extra charge as it was premium seat as per there statement. I requested them to see mybooking details it is clearly mentioned that seat no 7E, 7F alloted as per my selection during my booking alonv with my food.
As we are old and my spouse is medically unfit, we booked ticket along with seat and food more than one month before.
Kindly look into matter and help us.
Presently we are going by the flight as they have nit helped us. Waiting for your kind help.
In future we dont want to suffer and dont want to let suffer else.
